Automatic control method for shortwave transmitter beams considering power feedback
Because the traditional phase or amplitude control method cannot monitor the output power of the short-wave transmitter in real time,the beam pointing control accuracy is low,so the automatic control method considering power feedback is proposed.Build the mathematical model of the shortwave transmitter as the controlled object,monitor and modulate the output power signal of the short wave transmitter,and transmit the monitoring signal to the automatic tuning controller.The controller adjusts the gain of the shortwave transmitter amplifier according to the deviation between the monitoring signal and the target signal,and realize the automatic control of the transmitter beam pointing.The experimental results show that the offset is 0.6°.
